org.rhq.plugins.jmx.util.ObjectNameQueryUtility
A utility class to help in querying object names and utilizing parts of the object name for setting configuration values and changing string messages. A template that you'd build this utility with could look like "foo:name=%myName%,type=myType". This will be "translated" into a valid JMX objectName Query of the form "foo:type=myType,*". It will also detect that we've got a variable defined as "myName" that we'd like to later match to.
We can then find beans with the query and apply their objectName properties to the object and use those found values to rewrite strings or setup configuration properties. For example, we've got a detected object name for the above template "foo:name=bar,type=myType". We set its detected keys against this utility and we now have a variable defined as the key "myName" and the value of "bar". Then I can call formatMessage with "A foo called {myName}" which will be translated into "A foo called bar". This can be useful for naming resources and descriptions using parts of a mapped ObjectName. @author Greg Hinkle
